Android无法扩展Firebase Messaging Service [英] Android can't extend Firebase Messaging Service
问题描述
我正在尝试在我的应用程序中实施Firebase云消息传递,我已经实现了所有设置以使用此服务,但是当我尝试在我的类中扩展 FirebaseMessagingService
时,它给出了我的错误,它根本找不到它,我甚至无法导入com.google.firebase.messaging.FirebaseMessagingService
,如图所示:
I am trying to implement Firebase Cloud Messaging in my application, I had implemented all settings to use this service, but when I try to extend FirebaseMessagingService
in my class it gives me error and it can't find it at all, I can't even import com.google.firebase.messaging.FirebaseMessagingService
as shown in the picture:
我添加了所有必需的代码:
我将此添加到app gradle
I had added all the code required: I added this to app gradle
compile 'com.google.firebase:firebase-core:9.4.0'
apply plugin: 'com.google.gms.google-services'
这是module gradle:
and this to the module gradle:
classpath 'com.google.gms:google-services:3.0.0'
这是清单代码:
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<service
android:name=".MyFirebaseMessagingService">
<intent-filter>
<action android:name="com.google.firebase.MESSAGING_EVENT"/>
</intent-filter>
</service>
<service
android:name=".MyFirebaseInstanceIDService">
<intent-filter>
<action android:name="com.google.firebase.INSTANCE_ID_EVENT"/>
</intent-filter>
</service>
</application>
我将谷歌json文件添加到应用程序。
所以,如果有人可以帮助我,请
and I added the google json file to the app. So if anybody can help me please
推荐答案
如果你想使用消息传递,你必须添加消息传递模块。现在你只添加了核心模块。
If you want to use messaging, you have to add the messaging module. Right now you only added the core module.
所以继续并包括
compile 'com.google.firebase:firebase-messaging:9.4.0'
全部可在 https://firebase.google.com/docs/android/底部找到可用模块设置
